Finer points of rope-tailed chain rodes
Careful analysis of the various factors going into the choice between all-rope, all-chain and mixed anchor rodes has led many a sailor, including myself, to the conclusion that a rope-tailed chain rode indeed combines the best of both worlds, especially for sailors anchoring mostly at relatively similar depths.Two caveats are in order:(1) in anything but soft mud, try to keep the chain/rope splice clear off the bottom; and(2) when using a kellet (Terry's "sleeping pill") make sure the kellet slides well past the splice (i.e. onto the chain part of the rode).The reason is CHAFE. Those who regularly dive on their anchor rode will have observed how in relatively mild wind and wave conditions the same section of rode tends to get lifted off the sea bottom and dropped again endlessly. Having a kellet ride on the rope part of the rode, let alone sit on the splice, creates further risk of chafe. Since a direct rope/chain splice exposes the individual rope strands to extra chafe one should frequently inspect such splices and redo them, if necessary. Unfortunately, splicing braided high-stretch nylon (IMHO the best anchor rode since it does not twist under tension) to a chain rode is not an easy task and will generally require professional help.All in all, "Rivendel II" uses a full-chain rather than a rope-tailed chain rode. Largely because of the need to anchor in coral- and rock-infested places at widely varying depths. However, we ALWAYS attach a snubber consisting of (maximally) 25 ft of 3/4", high-stretch, braided nylon and equipped with a heavy chain hook.Have fun!Flying Dutchman
